Abstract

Phytotoxicity identification and selection of appropriate herbicides are important in nursery upkeep. Young oil palm seedling is susceptible to phytotoxicity that caused short-long term effect or worse lethal. The herbicides of various mode of action that commonly used in oil palm environment were selected for screening. The phytotoxicity observation and visual rating were done at 7, 14, 30 and 60 days after treatment. Topical spray was done at standard and high concentration rates. ANOVA with Fisher LSD method analysis at 95% confidence showed significant symptoms between treated and untreated treatment. There were two significant phytotoxicity effect groups. Which were- (i) severe to complete destruction - 2,4-dimethylammonium 60%, fluroxypyr-meptyl 45.5%, indaziflam 45.5%, triclopyr-butotyl 32.1% and glufosinate ammonium 24.5%. (ii) Slight to moderate - glyphosate isopropylamine 41%, MSMA 39.5% + diuron 7.8%, diuron 40% + ametryn 40%, metsulfuron-methyl 20% and diuron 80%. Use of hormonal and cellulose biosynthesis inhibitor mode of action close to seedling in nursery and during field planting should be avoided.
